The JBX88317 represents a premium solution for singlemode fiber optic connectivity, engineered to meet the demanding requirements of modern telecommunications and data center infrastructure. This 5-meter ST/ST duplex patch cable combines superior optical performance with robust construction for reliable long-term deployment. **Core Specifications & Performance:** Designed with a 9/125 micrometer core, this singlemode fiber cable supports long-distance transmission with minimal signal degradation. The G.657.A1 glass fiber specification ensures compatibility with standard telecom infrastructure while providing enhanced bend radius characteristics for easier installation. Attenuation performance of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm ensures minimal signal loss across critical transmission windows. The measured insertion loss of ≤0.35dB (typical 0.15dB) and return loss exceeding 20dB exceed industry standards for reliable optical coupling. **TAA Compliance & Quality Assurance:** This cable meets Trade Agreements Act requirements, making it suitable for government and institutional procurement. The RoHS/ELV compliance ensures environmental responsibility without compromising performance. Every cable undergoes attenuation testing per ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing consistent quality across production batches. The 90-day limited warranty provides peace of mind for mission-critical installations. **Physical Characteristics & Installation:** The compact 1.8mm outside diameter enables flexible routing through conduit and cable trays without excessive space consumption. OFNR riser-rated jacketing provides fire safety and durability in building plenum spaces. Type A to B crossover polarity configuration—the industry standard for duplex patch cords—ensures proper signal flow without adapter complications. **Ideal Applications:** This patch cable excels in telecommunications facilities, data center interconnects, laboratory test environments, and backbone network infrastructure. Custom lengths are available for specialized installations requiring non-standard configurations. **Availability & Support:** Ships from strategically located U.S. warehouses (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. Professional-grade construction combines with accessible pricing to deliver exceptional value for network infrastructure investments.
